[110] Animals can convert cyanocobalamin and hydroxocobalamin to the bioactive forms adenosylcobalamin and methylcobalamin by enzymatically replacing the cyano or hydroxyl groups

Its ability to activate sirtuins, enhance DNA repair, regulate metabolism, influence fat cell metabolism in preclinical models and support mitochondrial health positions it as a compelling candidate for further investigation

Blood tests including serum B12 levels can diagnose deficiency, and in some cases, additional tests such as intrinsic factor antibodies (to identify pernicious anaemia) may be appropriate

Sci Signal

The most direct way to study a proposed lipolytic agent is in isolated fat cells or adipose explants, measuring glycerol and free-fatty-acid release into the medium, cAMP accumulation, and the phosphorylation state of HSL
